Description
The Bel SRBA-06A1Ax modules are a series of non-isolated dc/dc converters that deliver up to 6 A of output
current with full load efficiency of 92% at 5.0 Vdc output. These modules pro Vide precisely regulated Voltage
programmable via external resistor from 0.75 Vdc to 5.0 Vdc over a wide range of input voltage (8.3 Vdc - 14
Vdc). The open-frame construction and small footprint enable designers to develop cost and space-efficient
solutions. Standard features include remote On/Off, over current protection, short current protection, wide input,
and programmable output voltage.
